Lt. Robert Martin said a man entered the Bank of America branch at One City Center shortly after 11 a.m. He passed the teller a note demanding money, and he left with an undisclosed amount of cash. Martin said he was not sure if the man said he was carrying a weapon.

Police released a screen grab of a suspected bank robber who robbed the Bank of America at One City Center in Portland on Thursday, Jan. 3, 2019.

“There were customers and tellers inside, and nobody was injured,” Martin said.

Martin said police are still looking for the robber, who is described as a white man carrying a backpack. He was wearing a tan jacket, sunglasses and what appeared to be a gray balaclava, Martin said.

The bank was closed while the police investigated the crime scene, and Martin was not sure if it would reopen Thursday afternoon.
